Provided is a method of producing a polycarbonate that enables efficient drying of a polycarbonate powder and has no risk of deteriorating the quality of a polycarbonate molded article to be obtained. The method of producing a polycarbonate includes: a step of causing an alkali aqueous solution of a dihydric phenol and phosgene to react with each other in the presence of an organic solvent to produce an organic solvent solution containing a polycarbonate; a powdering step of powdering the organic solvent solution containing the polycarbonate to provide a polycarbonate powder; and a pre-drying step of drying the polycarbonate powder to remove the remaining organic solvent, in which a drying temperature in the pre-drying step is set to a temperature lower than the glass transition temperature of the polycarbonate containing 1.5 mass % of the organic solvent by from 5 C. to 15 C.

A process for manufacturing biodegradable plastic from high percentage recyclable plastic feedstock and the product thereof. The process includes receiving recyclable plastic feedstock including high density polyethylene, low density polyethylene, expanded polyethylene, and stretched wrap, separating the plastic feedstock by plastics of like type, grinding the separated plastics into particulate while maintaining the temperature below said separated plastic's decomposition and melting point. The plastics are mixed in proportion, adding a biodegradable additive to the particulated plastic mixture with further mixing to produce the biodegradable plastic. Optionally, the resulting plastic is extruded for later use.
